YETI® Rambler® 18 oz (532 ml) Bottle with Straw Cap

The YETI Rambler 18 oz Bottle is an insulated stainless steel bottle for keeping water and other cold, non-carbonated drinks close at hand. The flip-up Straw Cap provides convenient upright sipping without tilting the bottle, while the integrated TripleHaul handle makes it easy to carry during hikes, training, travel, and everyday commutes.

Flip-Up Straw Cap

The Straw Cap opens with a simple flip and works with a wide internal straw for a steady flow. It allows you to drink while keeping the bottle upright, making it convenient during movement or when using the bottle in a vehicle.

Leakproof When Closed

The Straw Cap is leakproof when fully closed. However, it is not intended for loose transport inside a backpack or bag because strong movement or repeated impacts may cause the drinking spout to open. For pack transport, use a compatible fully secured Rambler Bottle cap.

Double-Wall Vacuum Insulation

Double-wall vacuum insulation helps keep cold drinks cold throughout the day. The bottle is made from kitchen-grade 18/8 stainless steel that resists punctures and rust during regular use.

TripleHaul Carry Handle

The integrated TripleHaul handle provides a secure grip for carrying the bottle by hand or removing it from a vehicle cupholder. The compact profile fits most standard cupholders.

Interchangeable Rambler Bottle Caps

All Rambler Bottle caps use the same interface. The supplied Straw Cap can therefore be replaced with a compatible Chug Cap, Commuter Cap, Cup Cap, or another Rambler Bottle cap selected for the intended drink and method of transport.

Use with Cold Drinks Only

The supplied Straw Cap is not designed for hot, carbonated, or pulpy beverages. The bottle should also not be used to store food or perishable contents. A compatible cap intended for hot beverages must be fitted if the bottle is used for coffee, tea, or another hot drink.

Easy to Clean

The bottle, cap, and straw are dishwasher safe. For thorough cleaning, remove the gaskets and place them in the utensil basket. The bottle is made from BPA-free materials.
